Abstract
The utility model relates to table lamp device fields, more particularly to a kind of desk lamp of adjustable intensity of illumination, it include: pedestal, lamp bracket, light bulb and controller, it is connected with the optical sensor for detecting intensity of illumination on the pedestal and adjusts the brightness regulation knob of bulb brightness, the controller changes bulb brightness by pulse width modulation circuit, infrared sensor and warning lamp are connected on lamp bracket, infrared sensor and warning lamp are electrically connected with controller, the intensity of illumination in desk lamp range of exposures is identified by optical sensor and is sent to controller, the intensity of illumination received is compared by controller with preset range, voltage, which is adjusted, by pulse width modulation circuit changes bulb brightness, keep intensity of illumination in the appropriate range, infrared sensor being capable of the distance between inductive desk lamp and human body simultaneously, when hypotelorism, infrared sensing Device sends signal to controller, and controller control warning lamp lights, plays a warning role, prevent from causing to damage to eyes.
Description
Technical field
The utility model relates to table lamp device field more particularly to a kind of desk lamps of adjustable intensity of illumination.
Background technique
Desk lamp is one kind of lamp, and small and exquisite exquisiteness is convenient for carrying, and is predominantly disposed on desk or dining table, for illuminating it
Relatively small and concentrate with, the bright range of exposures of desk lamp, effect is confined to around desk lamp, easy to read, study, work,
The energy is saved, traditional desk lamp intensity of illumination can not be adjusted, and intensity of illumination is too high or too low all to be unfavorable for regarding to eyes nocuousness
Power health.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and providing one kind makes desk lamp
The desk lamp of the adjustable intensity of illumination of intensity of illumination in the reasonable scope.
The utility model is to be achieved by the following technical programs:
A kind of desk lamp of adjustable intensity of illumination characterized by comprising pedestal, lamp bracket, light bulb and controller,
It is connected with the optical sensor for detecting intensity of illumination on the pedestal and adjusts the brightness regulation of bulb brightness
Knob, the controller change bulb brightness by pulse width modulation circuit,
Infrared sensor and warning lamp are connected on the lamp bracket, the infrared sensor and warning lamp are electric with controller
Property connection.
Preferably, electronic calendar is connected on the pedestal.
Preferably, fan is connected on the pedestal.
Preferably, electronic alarm clock is connected on the pedestal.
The beneficial effects of the utility model are:
The intensity of illumination in desk lamp range of exposures is identified by optical sensor and is sent to controller, and controller will receive
To intensity of illumination be compared with preset range, by pulse width modulation circuit adjust voltage change bulb brightness, keep illumination strong
Degree keep in the appropriate range, while infrared sensor can the distance between inductive desk lamp and human body, it is red when hypotelorism
Outer sensor sends signal to controller, and controller control warning lamp lights, plays a warning role, prevent from causing to damage to eyes
Wound.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
In figure: 1. pedestals, 2. lamp brackets, 3. light bulbs, 4. optical sensors, 5. brightness regulation knobs, 6. infrared sensors, 7.
Warning lamp, 8. electronic calendars, 9. fans, 10. electronic alarm clocks.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes: pedestal 1, lamp bracket 2, light bulb 3 and controller,
It is connected with the optical sensor 4 for detecting intensity of illumination on the pedestal and adjusts the brightness regulation of bulb brightness
Knob 5, the controller change bulb brightness by pulse width modulation circuit, and optical sensor is by the illumination in desk lamp range of exposures
Strength information is sent to controller, and the information received is compared by controller with reserved information, if the information received
Having exceeded reserved range of information, then controller changes the voltage to light bulb by pulse width modulation circuit, thus change bulb brightness,
Until intensity of illumination is being reserved in range of information, thus realize the dynamic adjustment of light bulb intensity of illumination, meanwhile, user can also root
Bulb brightness is adjusted either manually or by brightness regulation knob according to individual demand, the intensity of illumination after adjusting still can be in the tune of controller
Under section in reserved range of information,
It is connected with infrared sensor 6 and warning lamp 7 on the lamp bracket, the infrared sensor and warning lamp are and controller
It is electrically connected, infrared sensor can incude the distance between human body and light bulb, and when hypotelorism, infrared sensor is to control
Device sends signal, and controller control warning lamp lights, plays a warning role, prevent from causing to damage to eyes.
Preferably, it is connected with electronic calendar 8 on the pedestal, user is facilitated to check calendar and remarks backlog in time.
Preferably, it is connected with fan 9 on the pedestal, auxiliary temperature-reducing can be played the role of.
Preferably, it is connected with electronic alarm clock 10 on the pedestal, can be used for setting each study and work time, avoids growing
Time bends over the desk to cause eye fatigue, affects vision.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
